The Towers Watson report, Extreme Risks 2013, says the top 15 risks now for the first time include stagnation, health progress backfire, nuclear contamination, extreme longevity and terrorism.

Those that have dropped out of the top 15 this year are eurozone breakup, hyperinflation, political crisis, major war, end of fiat money and killer pandemic.

It says considering extreme risks can be useful in helping to design more robust investment portfolios and more robust risk management processes.

“To navigate through this complex world,” concludes the report, “we suggest investors need to be open-minded, avoid concentrated risks, be sensitive to early warning signs, constantly adapt and always prepare for the worst.”
